This link is maintained to preserve external references.\n\n## Original Description\nTraefik versions 3.7.0 through 3.7.6 contain a namespace confusion vulnerability in the Kubernetes Gateway API provider. When resolving HTTPRoute.spec.rules[].backendRefs[].filters[].extensionRef, Traefik used the backend Service namespace instead of the HTTPRoute namespace. A low-privileged route author holding a ReferenceGrant for a cross-namespace Service could therefore bind a Traefik Middleware from the backend namespace without a separate grant for that middleware, potentially injecting trusted reverse-proxy identity headers into downstream requests. The issue is fixed in version 3.7.7.","public_affected_ranges":[">= 3.7.0, < 3.7.7"]}],"null_published_at":"2026-11-03T10:03:26.534Z","source_updated_at":"2026-08-05T21:49:08.000Z","source_disclosed_at":"2026-07-22T12:32:18.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-03T09:58:09.980Z"}],"next_cursor":null,"snapshot_revision":"42594"}
